To @ZZ whom it may concern:

Beit known that I, HJALMAR Cirnrsrnn- SEN, a citizen of the United States of America, and a resident of the city oi' Seattle,` in the county of King and State of Washington, have invented certain new and usefulV linproveinents in Signs, oi which the following is a speciiication.

My invention has for its primary object to provide an illuminated sign in which the letters or symbols will be presented by bold and clearly-defined faces during the day and in brilliant clear-eut forrrs uji night,

'VVitiL' the above and otiifr desirable objects referred to in the iciloiving viewsmy in vention resides in the construction, combination, and arrangement of parts, as set forth in this s ecification and defined in the ap-` pended c aims. y

Referring to the accompanying drawings, in which similar refercncemunierals designate correspondingl parts throughout., Figure 1 is a front elevation of a letteror symbol constructed in accordance with my invention. Fig. 2 is a vertical sectional view taken on line 2 2 of Fig.A l; and Fig. 3 is a fragmentary view in perspective, showing.

the sections of 'the letter-traine separated fromeac'h other.

In the embodiment ot the invention Tprovide facings, as 1, shaped in accordance with the t e of letters or symbols desired and forme with broad limb portions or component parte in which are openings, as 2, in ther forni of letters or symbols. 'iheopeniiig l appears in the facing i a narrow slit and is, as shown, of such. general outline as to present the ap carence oiE the saine letter or symbol of, a iiierent type as that oi' the facing.

Reerence-nunieral 3 designates a leiterframe connected with facing i and secured to a suitable support or backing, as 4, the said frame conforming in shape to the outline ofthe facing, but having its wall spaced `inwardly from the margin oi said facing, so

that theJ latter will beprcsented iii bold relief in iront of the support or backing.

The frame 3 is pretei'ably composed of see-4 tions 5 and 6, fitting snugly but slidably one within the other and provided with lugs 5 and 6', respectively', which are secured to the facing 1 and support or backing 5, respectively.

Within the frame 3 are illuminating means, conveniently consisting et'I electriclight bulbs, as 7, which have screw-threaded connection With respective'sochets 8, secured to the support or backing 4. The Width of opening 2 is considerably lessthan the diameter of the light-bulb?, and l preferably provide opposite inwardly-diverging surfaces,

as 2', adjacent the outer end portions of said bulbs, which conveniently consist of they Walls of a recess 9, forme in the back tion of facing 1 along said o eningl surfaces serve to interce t iighbrays emanating from the light-bul s and reiiect them within the light-chamber 3 i'or a more even distribution of the light-rays, thereby cans ing the openings 2 to appear at night in bril- ..liant and clearly-defined form without obtaining a glaring and dazzling effect.

it will be observed that the width of the',

o enine 2 is considerably less than that of liinzbs of facing i, and in consequence the said opening will be scarcely observed in the day-time when reading the sign.

The elevation at which the sign stands above the street-level governs the amount of light required to give a readable eil'ect to the openings 2 at night and also, to -a certain ex- T esev tent, governs thi` distance that the facing 1 l shouid stand ofil from the support or backing to obtain a clear bold readable effect during the day. The higher the sign is placed the greater the strength of light required and the greater the degree thatthc facings should 1 stand oil' from the support or backing.

B v employing the telcscoping or extensible letter-immo 3 it is obvious that the facing 1 can be readily adiustcd to accommodate light-bulbs of the required power to (five the i amount ol light desired, thc degree oipadjustnient required to accommodate the length of thc lomp-bulb employed at a viven elevation oi they sign being substantially the same as required to bring the facing 1 the proper distance from the support or backing. i

When desired to replaceor substitute the lightehulbs, the facing 1 is removed, with its IOO frame-section, to give access to the lightchamber. I

Having thus described my invention, what l claim new, and desire to secureby Letters Patent of the United States of` America, isi In a sign, a chamber having an ,opening forming a letter or symbol, electric lamps in said chamber, there being rearwardl -diverging reflecting-surfaces at opposite .si es of said opening, between which said lamps project.

2. In a sign, an extensible 'trame comprisin sections in the form of a letter or s 'mbol fittingI one within another.

3. .n a sign, an extensible frame, electric lights removably supported therein, and a facing carried by said frame havingT an openmg inthe form of a letter or symbo 4t. In a sign, a chamber formed with extensible and contractibleside Walls, and an end y forming a letter or Wall having an opening symbol, and electric-light bulbs removably supported in said chamber. y

5. In a sign, an extensible frame, 'electric i. lights removably sup ort'ecll/vtherein, and. a

facing in the form of a etter orsymbol carried.

by sanlfrmne having an opening forming a second letter or symbol.

6. In a sign, a backing, a facing in the form of a letter or' symbol, and extensible means to movably support said facing for vadjustment relatively to said backing.

7. .In a sign, a backing, electric lights removably mounted thereon, and anextensible letter-trame embracing said lights.

8. In a sign, a backing, aletter-framo proe jecting therefrom, a facing at the outer edge of said frame in the form of a'letter or symbol, said Jfacing projecting laterally from the outer sides of the frame and having an opening forming a letter or symbol, and illuminating meanssupported in said frame. y

9. In a sign, a backing, aframe projecting therefrom; electric-light bulbs supported in said frame, and a facing on said frame in the form of a letter or symbol having an opening formin a letter or symbol, said opening being of Ie bulbs.

l0. In a sign, a backing, an extensible letter-frame projecting therefrom, electric-light bulbs removably supported in said frame, a facing on said frame in the form of a letter or symbol having an opening forming a second letter or symbol, said openin T being of less I Width than the diameter' of said bulbs, there being rearWardly-diverging reflecting-sur faces at opposite sides of said opening.

1 1. In a sign, a facing in the form of a'letter or symbol having an opening forming a letter or symbol, there being reliecting-surfaces at l oppite sides of said opening diverging reari. War y. l
